GEORGE MORGAN, 0F BINGHAM'ION, NEXIV YORK.-

GUARD FOR BUFFING WHEELS.

Application filed September To all whom it may concern citizen of the United States, and a resident of Binghamton in thecounty of Broome and State of New York haveinvented a and .Improved Guardfor Bufling Wheels, of which the following is a. full This invention relates to improvements in shoe machine guards an object of the in-,-

vention being to provide a guardfor the buffing wheels of shoe machinery and the like, which can be conveniently attached .to the machine and which will function to prevent scarring of uppers, over-counters, and back stays of shoes whlle bufhng the heels of the shoe.

.' A further object is to provide a guard of the character stated which is' capable of V movementvrelativeto the butting wheel to allow the sandpaper or other surface of the wheel to be removed and replacedas occasion may require. c

A further object is to provide an improved mounting for the guard which permits of adjustment thereof to compensate for different heights of shoe heel onwhich the 0perator is working.

A further object is to provide a guard of the character stated which functlons as a'guide and which not only lmproves the operation of buffing the heel because of the fast that'it prevents injury to other parts of the shoe, but because of the fact that the guard acts asa guide and'permits a more rapid operation than is possible without the same. 7

Vi ith these and otherobjects in view the invention consists in certain novel features.

of construction and combinations and arrangement's of parts as will be morefully hereinafter described and pointed out in the claims In the'accompanying drawings- Figure 1 is a fragmentary view partly in 'elevatlonand partly-in longitudinal section illustrating my improved guard in 'oper ative position relative to the bufling wheel of the'shoe machine or thelike.

r indicateda fragmentary portion 1 of a'shoe' Be it known that L GEORGE MORGAN, a

machine frame in which a shaftfl is supported and 'on said shaft-2 a buffing wheel 3 is secured. This bufiing wheel Sis-of the ordinary type having' a removable outer strip or sheet'of sandpaper 4s-or'other sim-' ilar material, which is removably connected to the wheel with the ends thereofclamped I .in'a slot orreces'sed portion 5 as is common in theart, so that when'the surface of the wheel becomes worn, the strip or'sheet can be replaced.

I Grepresents a bracket which is provided with a supporting arm -7 adaptedto be secured to the frame -1of the machine "by means of'a pairof screWsS, althoughit is obvious that the bracket might'be "Otl1e1" stitutes-an integral or fixed portion of an adjusting sleeve 13, the 'latter-jhavingrotary mounting'in the outer portion of bearing 9 and held against longitudinalmove ment by means of'a screw 14 which projectsithrough the bearing 9am into-en annular groove 15 in the sleeve. The 'sle'eve 13is made with an internally screw threadecl"b ore1'6 which receives' a screw threaded extension 17 on-"therod'll so that when the hand wheel 12 is turned, it will compel the longitudinal adjustment of 'therod 11in the bearings 9 and 1'O-for a purpose which will hereinafter appear.

18 represents myimproved guard which is in the form 'offa curved arnrv adapted to be positioned close to'the periphery of the bufiing wheel and having a straight orflat face 19'against which the heel of'the shoe v is'to befplaced to limit"theniovementof openings 20, which receive'the rod 11 be-- tween the bearings 9 and 10 and permit a pivotal movement of the guard on the rod.

A collar 21 is located on the'rod 11 within the bifurcated portion of guard-18 and this collar is secured to the rod 11 by means of a jam screw-22 lockingfthe collar and the rod together, preventing independent move-' ment thereof in any direction. 'A finger 23 is formed on the collar'21andengages un-Y.

-mal operative position,

der the bracket 6 so as to prevent turning movement of the rod in one direction.

This collar 22 is formed in its upper portion with a socket 24 into which a spring pressed pin carried by the guard 18 is adapted to fit so' that when said pin is in the socket, the guard will be held in its norl/Vhen the spring pressed pin is withdrawn from the socket 2 l,' ;the guard can be swung downwardlyLto the "dot and dash line position shownin Figure 2, so that the cover of the 'bufiing wheel can be changed and not interfere with the operation of su-ch changing.

The operation is asfollows? By refer ence particularly to Figure 1, it will be noted that the st aight. or flat face 19 of the guard 18 is parallel with the edgeof the bufling wheel 3 andis spaced from said edge; a distance equal to the height of the heel to be buffed.

Hence,1an operator can quickly buff the heels and shoes by placing the bottoms of the heels against the guard 18 and ;the edges of the heels against the surface of the bufling wheel so that said heels: can be i properly and quickly buffedwithout any adj ustmen-t.

danger of "injuring other portions of. the .shoe; AS the height of shoe heels varles, it

is necessary to provide a lateral ad ustment- "i Nhen it is desired to change the surface of the; buffing wheel, it is simply necessary to withdraw the spring pressed pm 25 from the socket 24 and the guard can be swung downwardly, as shown Figure .and after :the bulling wheel is properlysurfaced; the guard can be swung back to oper gative position and the spring pressed pin 25 will automatically engage in I th socket 24 1 -posi tion,

and i hold the guard in, proper operative Various slight changes'might be made in the general form and arrangement of the parts described without departing fromthe invention, and hence I do not limit myself I to the precise details set forth, but: consider myself at liberty .to make such changes and falterations as fairly fall within the spirit and; scope of the appended claims.
